The present invention relates to a multiple processing machine having a punch press for punching a sheet-like workpiece and a ram-operated forming press for performing a variety of forming operations such as bending, shearing, and drawing on the workpiece The punch press and forming press are interconnected with each other along a central partition A feeding device is also provided adjacent the punching and forming press on a central worktable In addition, a tool changing device is provided to change the tools in either or both of the punching and forming presses

Multiple processing machine

There is described a machine for machining metal sheets, which
comprises a bending machine (1) for bending sides of a metal sheet (50) and
a manipulator-rotator (3) that is mobile in relation to the bending machine
(1) for automatic positioning of the metal sheet (50) during bending. The
machine comprises at least one punching press (21, 30) for punching said
metal sheet (50), that is served by said manipulator-rotator (3) so that said
manipulator-rotator (3) is utilised for automatic positioning of the metal
sheet (50) both during bending and during punching of the metal sheet (50).

The invention relates to a method for the synchronised operation of machines comprising a plurality of axes (102, 110, 111). Said axes (102, 110, 111) are actuated by means of a respective associated single drive (103) in a synchronised manner according to an electronic, chronological control axis function which corresponds to a momentary position of a control axis L. The movements of a plurality of guided axes (102, 110, 111) according to translation functions corresponding to respectively predetermined, mechanical translations (106, 107, 108, 109) in relation to the control axis L are derived from said control axis L in order to improve upon said method. According to the invention, it is possible to adjust a large number of axes and ensure easy operation, requiring only a relatively small amount of apparatus by making all axes (102) of at least one group (117) of axes corresponding to each other with respect to mechanical translation (106, 107, 108, 109) follow an electronic, chronological sequential control function which corresponds to a momentary position of a sequential axis F and which is formed by combining the relative translation and control axis functions.

A stamping and bending machine (10) has upper and lower horizontal supports (18, 16) in each of which are formed two longitudinal chambers (80) which open out through broad longitudinal slits (86) on opposite sides of the horizontal supports (16, 18). On both lateral faces of the horizontal supports (16, 18) carriage assemblies (26) are fixed; each of these carries an angular gear (36) which is encapsulated in a gear housing and protrudes through the longitudinal slit (86) into the appropriate longitudinal chamber (80). The angular gears (36) in each longitudinal chamber (80) are provided with coaxial through-channels with polygonal profiles. A drive shaft (28) with matching polygonal profiles is inserted through the angular gear (36) of each longitudinal channel (80) and couples the carriage assemblies (26) together. All the bearings of the gear teeth of the angular gear (36) and output shaft in the carriage assembly (26) are arranged in the modular unit formed by the carriage assembly (26) and angular gear (36). The drive shaft (28) is supported by the angular gear (36) and thus requires no bedding of its own in the horizontal supports (16, 18) of the machine housing (14).

In a method and a device for producing curved lengths of spring band steel in order to produce precisely toleranced, dimensionally stable bending radii, the spring band steel (10) pass through a bending unit (20), which is comprised of three support points (23-25) spaced apart from one another, and passes through a reverse bending unit (22), which is disposed after the bending unit (20) in the advancing direction of the spring band steel (10) and is comprised of a fourth support point (32), and in a cutting unit (21), the curved and recurved lengths of spring band steel (11) are cut from the spring band steel (10) The central support point (24) of the bending unit (20) and the fourth support point (32) of the reverse bending unit (22) are embodied so that they can be moved and are controlled in their advancing in relation to the spring band steel (10) by means of a numerical control unit (20) in accordance with predetermined programs (FIG 1)

A stamping and bending machine, having modular structure, comprises a drive unit, a pull-in feed system, a stamping press and one or several bending appliances are disclosed. Every bending appliance comprises one top and one bottom box of oblong shape forming a closed frame thanks to spacing elements. Within every box, there are two drive shafts which actuate bending attachments provided on the front and rear faces of the top as well as of the bottom boxes. The drive shafts of stamping press and of all bending appliances are coupled frontally. The shafts will all be driven at the same high speed, stepping down being performed not earlier than at a take-off gearing comprised in any bending attachment.
